Prolific is an online platform founded in 2014 that connects researchers, AI developers, and product teams with vetted participants for studies and data collection. The platform grew out of academic research at Oxford University and has since scaled to serve over 35,000 organisations, including leading universities, AI companies, and Fortune 500 firms. A new study launches on the platform every two minutes.
The platform maintains a pool of more than 200,000 active verified participants spanning 38+ countries and supporting research in over 80 languages. Participants are fairly compensated for their time, and the platform emphasises data quality through participant vetting and engagement. Use cases range from academic and behavioural research to AI training data collection and product testing.
Prolific's technical scope covers the full research data pipeline: participant recruitment, multilingual study deployment, and human-derived data collection at scale. Its infrastructure supports the varied needs of academic institutions conducting peer-reviewed research, AI teams requiring high-quality human feedback, and enterprise product teams running user studies.
